in which to R1 to R10 and X1 and X2 have the meanings given in the description, and agrochemically active salts thereof, their use and also methods and compositions for controlling phytopathogenic harmful fungi in and/or on plants or in and/or on seed of plants, processes for preparing such compositions and treated seed and also their use for controlling phytopathogenic harmful fungi in agriculture, horticulture and forestry, in the protection of materials and in the domestic and hygiene field. The present invention furthermore relates to a process for preparing thienylaminopyrimidines of the formula (I).

Description

  • The invention relates to thienylaminopyrimidines and their agrochemically active salts, to their use and to methods and compositions for controlling phytopathogenic harmful fungi in and/or on plants or in and/or on seed of plants, to processes for preparing such compositions and treated seed and also to their use for controlling phytopathogenic harmful fungi in agriculture, horticulture and forestry, in the protection of materials and in the domestic and hygiene field. The present invention furthermore relates to a process for preparing thienylaminopyrimidines.
  • Since the ecological and economic demands made on modern crop protection agents are increasing constantly, for example with respect to activity spectrum, toxicity, selectivity, application rate, formation of residues and favourable manufacture, and there can furthermore be problems, for example, with resistance, there is a constant need to develop novel fungicides which, at least in some areas, have advantages over the known fungicides.
  • Surprisingly, it has now been found that the present thiophene-substituted aminopyrimidines solve at least some aspects of the objects mentioned and are suitable for use as crop protection agents, in particular as fungicides.
  • Sulphonamide-substituted thiopheneaminopyrimidines are already known as pharmaceutically active compounds (see, for example, WO 03/076437), but not their surprising fungicidal activity.

  • where the definitions of the radicals R1 to R9 and X1 and X2 in the above schemes correspond to the given definitions and Y and Hal represent F, Cl, Br, I.
  • One way of preparing compounds of the formula (V) is shown in Scheme 1.
  • The alkylamino compounds of the formula (II) are either commercially available or can be prepared by literature procedures. One method for preparing suitable cyclopropylamino compounds of type (II) is, for example, the rearrangement of suitable carboxylic acid derivatives to the corresponding amino compounds (described, for example, in J. Am. Chem. Soc. 1961, 83, 3671-3678). Other methods, for example for preparing cyclobutylamino compounds of type (II), comprise the hydroboration of suitable cyclobutenes and subsequent treatment with NH2SO3H (for example Tetrahedron 1970, 26, 5033-5039), the reductive amination of cyclobutanones (described, for example, in J. Org. Chem. 1964, 29, 2588-2592) and also the reduction of nitro- or nitrosocyclobutanes (see, for example, J. Am. Chem. Soc. 1953, 75, 4044; Can. J. Chem. 1963, 41, 863-875) or azidocyclobutanes (described, for example, in Chem. Pharm. Bull. 1990, 38, 2719-2725; J. Org. Chem. 1962, 27, 1647-1650). The halogen-substituted amino compounds of the formula (II) are either commercially available or can be prepared by literature procedures. One method for preparing suitable halogen-substituted amino compounds (II) is, for example, the reduction of corresponding carboxamides (described, for example, in EP30092) or corresponding oximes or azides (described, for example, in Chem. Ber. 1988, 119, 2233) or nitro compounds (described, for example, in J. Am. Chem. Soc, 1953, 75, 5006). A further alternative consists in the treatment of corresponding aminocarboxylic acids with SF4 in HF (described, for example, in J. Org. Chem. 1962, 27, 1406). The ring-opening of substituted aziridines with HF is described in J. Org. Chem. 1981, 46, 4938. Further methods for preparing halogen-substituted amino compounds (II) comprise the cleavage of corresponding phthalimides according to Gabriel (described, for example, in DE 3429048), the aminol ysis of suitable haloalkyl halides (described, for example, in US2539406) or the degradation of corresponding carboxylic acid azides (described, for example, in DE3611195). Using suitable fluorinating agents (for example DAST), aminoaldehydes or -ketones can be converted into the corresponding difluoroalkylamines (WO2008008022), whereas amino alcohols form the corresponding monofluoroalkylamines (for example WO2006029115). Analogously, using suitable chlorinating and brominating agents, chloro- and bromoalkylamines, respectively, can be obtained from amino alcohols (J. Org. Chem. 2005, 70, 7364, or Org. Lett., 2004, 6, 1935).
  • Suitable substituted 2,4-dihalopyrimidines (III) are either commercially available or can be prepared according to literature procedures, for example from commercially available substituted uracils (for example R7═CN: J. Org. Chem. 1962, 27, 2264; J. Chem. Soc. 1955, 1834; Chem. Ber. 1909, 42, 734; R7═CF3: J. Fluorine Chem. 1996, 77, 93; see also WO 2000/047539).
  • Using a suitable base at a temperature of from −30° C. to +80° C. in a suitable solvent, such as, for example, dioxane, THF, dimethylformamide or acetonitrile, initially an amine (II) is reacted with a 2,4-dihalopyrimidine (III) over a period of 1-24 h. Suitable for the use as base are, for example, inorganic salts, such as NaHCO3, Na2CO3 or K2CO3, organometallic compounds, such as LDA or NaHMDS, or amine bases, such as ethyldiisopropylamine, DBU, DBN or tri-n-butylamine. Alternatively, the reaction can also be carried out as described, for example, in Org. Lett. 2006, 8, 395 with the aid of a suitable transition metal catalyst, such as, for example, palladium, together with a suitiable ligand, such as, for example, triphenylphosphine or xanthphos.

  • One way of preparing compounds of the formula (IV-1) is shown in Scheme 6.
  • Substituted aminothiophenes (IV-1) can be prepared, for example, by reacting commercially available and appropriately substituted nitrothiophenes (XI) with reducing agents (for example iron powder, zinc powder, tin powder, see, for example, Heterocycles 2005, 65, 2369-2380) in suitable solvents, such as, for example, acetic acid or hydrochloric acid, at temperatures of from 20° C. to 150° C., but preferably from 70° C. to 90° C. (Scheme 6).
  • One way of preparing compounds of the formula (IV-3) is shown in Scheme 7.
  • One method of synthesizing thiophenecarbamates of the formula (IV-3) consists in reacting commercially available thiophenecarboxylic acids (IV-2, Scheme 7) with organic azides (XII), such as, for example, phosphoryl azide, in the presence of a suitable base (for example triethylamine, diisopropylamine), using suitable solvents (for example tert-butanol, benzyl alcohol), to give the corresponding thiophenecarbamates (IV-3) (see, for example, WO 2007/076423; Bioorg. Med. Chem. Lett. 2006, 16, 5567-5571).
  • One way of preparing compounds of the formula (I) from compounds of the formula (IV-3) is shown in Scheme 8.
  • Here, the intermediate (V) is reacted in the presence of Brönsted acids, such as, for example, anhydrous hydrochloric acid, camphorsulphonic acid or p-toluenesulphonic acid, in a suitable solvent, such as, for example, dioxane, THF, DMSO, DME, 2-methoxyethanol, n-butanol or acetonitrile, at a temperature of 0° C.-140° C. over a period of 1-48 h with a thiophenecarbamate (IV-3).
  • One way of preparing compounds of the formula (Ib) is shown in Scheme 9.
  • Thus, for example, alkoxycarbonyl-substituted thienylaminopyrimidines of type (Ia) obtainable by the process shown in Scheme 2 can be converted, if appropriate in the presence of an acid and in the presence of a solvent, and are then hydrolyzed by reaction with suitable bases, such as, for example, NaOH or KOH, in suitable solvents, such as, for example, water, to give the corresponding carboxylic acid-substituted thienylaminopyrimidines (Ib) (see, for example, J. Med. Chem. 1986, 29, 1637-1643).
  • One way of preparing compounds of the formula (Ic) is shown in Scheme 10.
  • By reacting the carboxylic acid-substituted thienylaminopyrimidines (Ib) with amines using generally known coupling agents (for example bromotrispyrrolidinophosphonium hexafluorophosphate, PyBrop) in the presence of an auxiliary base and in the presence of a solvent, it is possible to generate the corresponding carboxamide-substituted thienylaminopyrimidines (Ic) (see, for example, WO 06/040569).
  • One way of preparing compounds of the formula (IX) is shown in Scheme 3.
  • 2-Halo-substituted pyrimidin-4-ones (VI) are available by regioselective hydrolysis from 2,4-dihalo-substituted pyrimidines. This is described, for example, in Russ. J. Org. Chem. 2006, 42, 580; J. Med. Chem. 1965, 8, 253.
  • Intermediates of the formula (VI) are reacted in the presence of Brönsted acids, such as, for example, anhydrous hydrochloric acid, camphorsulphonic acid or p-toluenesulphonic acid, in a suitable solvent, such as, for example, dioxane, THF, DMSO, DME, 2-methoxyethanol, n-butanol or acetonitrile, at a temperature of 0° C.-140° C. over a period of 1-48 h with a thiophenamine (IV).
  • Alternatively, the reaction of (VI) and (IV) to give (IX) can also be carried out with base catalysis, i.e. using, for example, carbonates, such as potassium carbonate, alkoxides, such as potassium tert-butoxide, or hydrides, such as sodium hydride, where the catalytic use of a transition metal, such as, for example, palladium, together with a suitable ligand, such as, for example, xanthphos, may also be useful.
  • Finally, it is possible to carry out the reaction of (VI) and (IV) to give (IX) in the absence of solvents and/or Brönsted acids (described, for example, in Bioorg. Med. Chem. Lett. 2006, 16, 108; Bioorg. Med. Chem. Lett. 2005, 15, 3881).

  • If appropriate, the active compounds according to the invention can also be used in certain concentrations and application rates as herbicides and for influencing plant growth, and also for controlling animal pests. If appropriate, they can also be employed as intermediates and precursors for the synthesis of further active compounds.
  • The active compounds according to the invention, in combination with good plant tolerance and favourable toxicity to warm-blooded animals and being tolerated well by the environment, are suitable for protecting plants and plant organisms, for increasing harvest yields and for improving the quality of harvested material. They are preferably employed as plant protection agents. They are active against normally sensitive and resistant species and against all or some stages of development.
  • The treatment according to the invention of the plants and plant parts with the active compounds or compositions is carried out directly or by action on their surroundings, habitat or storage space using customary treatment methods, for example by dipping, spraying, atomizing, irrigating, evaporating, dusting, fogging, broadcasting, foaming, painting, spreading-on, watering (drenching), drip irrigating and, in the case of propagation material, in particular in the case of seeds, furthermore as a powder for dry seed treatment, a solution for seed treatment, a water-soluble powder for slurry treatment, by encrusting, by coating with one or more coats, etc. It is furthermore possible to apply the active compounds by the ultra-low-volume method or to inject the active compound preparation or the active compound itself into the soil.
  • The application rate of active compound can vary within a substantial range. Essentially, it depends on the nature of the desired effect. In general, the application rates are between 1 g and 10 kg of active compound per hectare of soil area, preferably between 5 g and 5 kg per ha.
  • The advantageous effect of the compatibility with crop plants of the active compounds according to the invention is particularly pronounced at certain concentration ratios. However, the weight ratios of the active compounds in the active compound combinations can be varied within relatively wide ranges. In general, from 0.001 to 1000 parts by weight, preferably from 0.01 to 100 parts by weight, particularly preferably 0.05 to 20 parts by weight, of one of the compounds which improves crop plant compatibility (antidotes/safeners) mentioned above under (b′) are present per part by weight of active compound of the formula (I).
  • The active compounds according to the invention are generally applied in the form of finished formulations. However, the active compounds contained in the active compound combinations can, as individual formulations, also be mixed during use, i.e. be applied in the form of tank mixes.
  • In addition, by the treatment according to the invention it is possible to reduce the mycotoxin content in the harvested material and the foodstuffs and feedstuffs prepared therefrom. Particular, but not exclusive, mention may be made here of the following mycotoxins: deoxynivalenol (DON), nivalenol, 15-Ac-DON, 3-Ac-DON, T2- and HT2-toxin, fumonisins, zearalenone, moniliformin, fusarin, diacetoxyscirpenol (DAS), beauvericin, enniatin, fusaroproliferin, fusarenol, ochratoxins, patulin, ergot alkaloids and aflatoxins produced, for example, by the following fungi: Fusarium spec., such as Fusarium acuminatum, F. avenaceum, F. crookwellense, F. culmorum, F. graminearum (Gibberella zeae), F. equiseti, F. fujikoroi, F. musarum, F. oxysporum, F. proliferatum, F. poae, F. pseudograminearum, F. sambucinum, F. scirpi, F. semitectum, F. solani, F. sporotrichoides, F. langsethiae, F. subglutinans, F. tricinctum, F. verticillioides, inter alia, and also by Aspergillus spec., Penicillium spec., Claviceps purpurea, Stachybotrys spec., inter alia.
  • In the protection of materials, the compositions or active compounds according to the invention can furthermore be employed for protecting industrial materials against attack and destruction by unwanted microorganisms, such as, for example, fungi.
  • In the present context, industrial materials are understood as meaning nonlive materials which have been made for use in technology. For example, industrial materials which are to be protected by active compounds according to the invention from microbial modification or destruction can be glues, sizes, paper and board, textiles, leather, timber, paints and plastic articles, cooling lubricants and other materials which are capable of being attacked or destroyed by microorganisms. Parts of production plants, for example cooling-water circuits, which can be adversely affected by the multiplication of microorganisms may also be mentioned within the materials to be protected. Industrial materials which may be mentioned with preference for the purposes of the present invention are glues, sizes, paper and board, leather, timber, paints, cooling lubricants and heat-transfer fluids, especially preferably wood. The compositions or active compounds according to the invention can prevent disadvantageous effects such as rotting, decay, discoloration, decoloration or the formation of mould.
  • The method according to the invention for controlling unwanted fungi can also be employed for protecting storage goods. Here, storage goods are to be understood as meaning natural substances of vegetable or animal origin or process products thereof of natural origin, for which long-term protection is desired. Storage goods of vegetable origin, such as, for example, plants or plant parts, such as stems, leaves, tubers, seeds, fruits, grains, can be protected freshly harvested or after processing by (pre)drying, moistening, comminuting, grinding, pressing or roasting. Storage goods also include timber, both unprocessed, such as construction timber, electricity poles and barriers, or in the form of finished products, such as furniture. Storage goods of animal origin are, for example, hides, leather, furs and hairs. The active compounds according to the invention can prevent disadvantageous effects, such as rotting, decay, discoloration, decoloration or the formation of mould.
  • Microorganisms capable of degrading or changing the industrial materials which may be mentioned are, for example, bacteria, fungi, yeasts, algae and slime organisms. The active compounds according to the invention preferably act against fungi, in particular moulds, wood-discoloring and wood-destroying fungi (Basidiomycetes) and against slime organisms and algae. Microorganisms of the following genera may be mentioned as examples: Alternaria, such as Alternaria tenuis; Aspergillus, such as Aspergillus niger; Chaetomium, such as Chaetomium globosum; Coniophora, such as Coniophora puetana; Lentinus, such as Lentinus tigrinus; Penicillium, such as Penicillium glaucum; Polyporus, such as Polyporus versicolor; Aureobasidium, such as Aureobasidium pullulans; Sclerophoma, such as Sclerophoma pityophila; Trichoderma, such as Trichoderma viride; Escherichia, such as Escherichia coli; Pseudomonas, such as Pseudomonas aeruginosa; Staphylococcus, such as Staphylococcus aureus.
  • The present invention furthermore relates to a composition for controlling unwanted microorganisms comprising at least one of the thienylaminopyrimidines according to the invention. These are preferably fungicidal compositions comprising auxiliaries, solvents, carriers, surfactants or extenders suitable for use in agriculture.
  • According to the invention, a carrier is a natural or synthetic, organic or inorganic substance with which the active compounds are mixed or bonded for better applicability, in particular for application to plants or parts of plants or seed. The carrier, which may be solid or liquid, is generally inert and should be suitable for use in agriculture.
  • Suitable solid carriers are: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates; suitable solid carriers for granules are: for example crushed and fractionated natural rocks, such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic meals, and granules of organic material, such as paper, sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam-formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and also protein hydrolysates; suitable dispersants are nonionic and/or ionic substances, for example from the classes of the alcohol/POE and/or POP ethers, acid and/or POP/POE esters, alkylaryl and/or POP/POE ethers, fat and/or POP/POE adducts, POE and/or POP polyol derivatives, POE and/or POP/sorbitan or sugar adducts, alkyl or aryl sulphates, sulphonates and phosphates, or the corresponding PO ether adducts. Furthermore suitable oligo- or polymers, for example those derived from vinylic monomers, from acrylic acid, from EO and/or PO alone or in combination with, for example, (poly)alcohols or (poly)amines. It is also possible to employ lignin and its sulphonic acid derivatives, unmodified and modified celluloses, aromatic and/or aliphatic sulphonic acids and their adducts with formaldehyde.
  • The active compounds can be converted to the customary formulations, such as solutions, emulsions, wettable powders, water- and oil-based suspensions, powders, dusts, pastes, soluble powders, soluble granules, granules for broadcasting, suspension-emulsion concentrates, natural materials impregnated with active compound, synthetic materials impregnated with active compound, fertilizers and also microencapsulations in polymeric substances.
  • The active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, emulsions, water- or oil-based suspensions, powders, wettable powders, pastes, soluble powders, dusts, soluble granules, granules for broadcasting, suspension-emulsion concentrates, natural materials impregnated with active compound, synthetic materials impregnated with active compound, fertilizers and also microencapsulations in polymeric substances. Application is carried out in a customary manner, for example by pouring, spraying, atomizing, broadcasting, dusting, foaming, painting-on, etc. It is furthermore possible to apply the active compounds by the ultra-low-volume method or to inject the preparation of active compound or the active compound itself into the soil. It is also possible to treat the seed of the plants.
  • The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one customary extender, solvent or diluent, emulsifier, dispersant and/or binder or fixative, wetting agent, water repellant, if appropriate siccatives and UV stabilizers and if appropriate colorants and pigments, antifoams, preservatives, secondary thickeners, glues, gibberellins and other processing auxiliaries.
  • The compositions according to the invention include not only formulations which are already ready to use and can be applied to the plant or the seed using a suitable apparatus, but also commercial concentrates which have to be diluted with water prior to use.
  • The active compounds according to the invention can be present as such or in their (commercial) formulations and also in the use forms prepared from these formulations as a mixture with other (known) active compounds, such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth regulators, herbicides, fertilizers, safeners and/or semiochemicals.
  • Suitable for use as auxiliaries are substances which are suitable for imparting to the composition itself and/or to preparations derived therefrom (for example spray liquors, seed dressings) particular properties such as certain technical properties and/or also particular biological properties. Typical suitable auxiliaries are: extenders, solvents and carriers.
  • Suitable extenders are, for example, water, polar and nonpolar organic chemical liquids, for example from the classes of the aromatic and non-aromatic hydrocarbons (such as paraffins, alkylbenzenes, alkylnaphthalenes, chlorobenzenes), the alcohols and polyols (which, if appropriate, may also be substituted, etherified and/or esterified), the ketones (such as acetone, cyclohexanone), esters (including fats and oils) and (poly)ethers, the unsubstituted and substituted amines, amides, lactams (such as N-alkylpyrrolidones) and lactones, the sulphones and sulphoxides (such as dimethyl sulphoxide).
  • Liquefied gaseous extenders or carriers are liquids which are gaseous at ambient temperature and under atmospheric pressure, for example aerosol propellants, such as halogenated hydrocarbons, and also butane, propane, nitrogen and carbon dioxide.
  • Tackifiers, such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules and latices, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, or else natural phospholipids, such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other possible additives are mineral and vegetable oils.
  • If the extender used is water, it is also possible to use, for example, organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatic compounds, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatic compounds or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol, and also ethers and esters thereof, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water.
  • The compositions according to the invention may additionally comprise further components, such as, for example, surfactants. Suitable surfactants are emulsifiers and/or foam-formers, dispersants or wetting agents having ionic or nonionic properties, or mixtures of these surfactants. Examples of these are salts of polyacrylic acid, salts of lignosulphonic acid, salts of phenolsulphonic acid or naphthalenesulphonic acid, polycondensates of ethylene oxide with fatty alcohols or with fatty acids or with fatty amines, substituted phenols (preferably alkylphenols or arylphenols), salts of sulphosuccinic esters, taurine derivatives (preferably alkyl taurates), phosphoric esters of polyethoxylated alcohols or phenols, fatty esters of polyols, and derivatives of the compounds containing sulphates, sulphonates and phosphates, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, protein hydrolysates, lignosulphite waste liquors and methylcellulose. The presence of a surfactant is required if one of the active compounds and/or one of the inert carriers is insoluble in water and the application is carried out in water. The proportion of surfactants is between 5 and 40 percent by weight of the compositions according to the invention.
  • It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide, Prussian blue, and organic dyes, such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
  • Other possible additives are perfumes, mineral or vegetable oils, if appropriate modified, waxes and nutrients (including trace nutrients), such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
  • Stabilizers, such as low-temperature stabilizers, preservatives, antioxidants, light stabilizers or other agents which improve chemical and/or physical stability may also be present.
  • If appropriate, it is also possible for other addition components to be present, for example protective colloids, binders, glues, thickeners, thixotropic agents, penetrants, stabilizers, sequestrants, complex fomers. In general, the active compounds can be combined with any solid or liquid additive customarily used for formulation purposes.
  • The formulations generally comprise between 0.05 and 99% by weight, 0.01 and 98% by weight, preferably between 0.1 and 95% by weight, particularly preferably between 0.5 and 90% by weight, of active compound, very particularly preferably between 10 and 70 percent by weight.
  • The formulations described above can be employed in a method according to the invention for controlling unwanted microorganisms where the thienylaminopyrimidines according to the invention are applied to the microorganisms and/or their habitat.
  • The active compounds according to the invention, as such or in their formulations, can also be used in a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, for example to broaden the activity spectrum or to prevent the development of resistance.
  • Suitable mixing partners are, for example, known fungicides, insecticides, acaricides, nematicides or else bactericides (see also Pesticide Manual, 13th ed.).
  • A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, safeners and/or semiochemicals is also possible.
  • Application is carried out in a manner adapted to the use forms.
  • The control of phytopathogenic harmful fungi is primarily by treating the soil and the above-ground parts of the plants with crop protection compositions. Owing to concerns with a view to a possible impact of the crop protection compositions on the environment and human and animal health, there are efforts to reduce the amount of active compounds applied.
  • The active compounds can be applied as such, in the form of their formulations and the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application is carried out in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, painting-on, etc. It is also possible to apply the active compounds by the ultra-low-volume method or to inject the preparation of active compound or the active compound itself into the soil. It is also possible to treat the seed of the plants.
  • When using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the type of application. The application rate of the active compounds according to the invention is
      • in the treatment of parts of plants, for example leaves: from 0.1 to 10 000 g/ha, preferably from 10 to 1000 g/ha, particularly preferably from 50 to 300 g/ha (when the application is by watering or dripping, it is possible to reduce the application rate even more, in particular when inert substrates such as rock wool or perlite are used);
      • in the treatment of seed: from 2 to 200 g per 100 kg of seed, preferably from 3 to 150 g per 100 kg of seed, particularly preferably from 2.5 to 25 g per 100 kg of seed, very particularly preferably from 2.5 to 12.5 g per 100 kg of seed;
      • in soil treatment: from 0.1 to 10 000 g/ha, preferably from 1 to 5000 g/ha.
  • These application rates are mentioned only in an exemplary manner and not limiting for the purpose of the invention.
  • The compounds according to the invention can also be used for protecting objects which come into contact with salt water or brackish water, such as hulls, screens, nets, buildings, moorings and signalling systems, against colonization.
  • The active compounds according to the invention, alone or in combination with other active compounds, can furthermore be employed as antifouling agents.
  • The treatment method according to the invention can be used for treating genetically modified organisms (GMOs), for example plants or seeds. Genetically modified plants (or transgenic plants) are plants in which a heterologous gene has been stably integrated into the genome. The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using for example, antisense technology, cosuppression technology or RNA interference—RNAi—technology). A heterologous gene that is located in the genome is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.
  • Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, the following effects, which exceed the effects which were actually to be expected, are possible: reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the active compounds and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, bigger fruits, larger plant height, greener leaf colour, earlier flowering, higher quality and/or a higher nutritional value of the harvested products, higher sugar concentration within the fruits, better storage stability and/or processability of the harvested products.
  • In the present case, unwanted phytopathogenic fungi and/or microorganisms and/or viruses are to be understood as meaning phytopathogenic fungi, bacteria and viruses. Thus, the substances according to the invention can be employed for protecting plants against attack by the abovementioned pathogens within a certain period of time after the treatment. The period of time within which protection is effected generally extends from 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with the active compounds.
  • Plants and plant cultivars which are preferably treated according to the invention include all plants with genetic material which bestows upon these plants particularly advantageous useful properties (whether this was achieved by breeding and/or biotechnology is immaterial).
  • Plants and plant cultivars which are also preferably treated according to the invention are resistant towards one or more biotic stresses, i.e. said plants have a better defense against animal and microbial pests, such as against nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.
  • Plants and plant cultivars which may also be treated according to the invention are those which are resistant to one or more abiotic stress factors. Abiotic stress conditions may include, for example, drought, cold temperature exposure, heat exposure, osmotic stress, flooding, increased soil salinity, increased mineral exposure, ozone exposure, high light exposure, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients or shade avoidance.
  • Plants and plant cultivars which may also be treated according to the invention, are those plants characterized by enhanced yield characteristics. Increased yield in said plants can be the result of, for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation. Yield can furthermore by affected by improved plant architecture (under stress and non-stress conditions), including early flowering, flowering control for hybrid seed production, seedling vigour, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pod dehiscence and lodging resistance. Further yield traits include seed composition, such as carbohydrate content, protein content, oil content and composition, nutritional value, reduction in anti-nutritional compounds, improved processability and better storage stability.
  • Plants that may be treated according to the invention are hybrid plants that already express the characteristics of heterosis or the hybrid effect which results in generally higher yield, vigour, health and resistance towards biotic and abiotic stress factors. Such plants are typically made by crossing an inbred male sterile parent line (the female parent) with another inbred male fertile parent line (the male parent). Hybrid seed is typically harvested from the male sterile plants and sold to growers. Male sterile plants can sometimes (e.g. in corn) be produced by detasseling, (i.e. the mechanical removal of the male reproductive organs or male flowers) but, more typically, male sterility is the result of genetic determinants in the plant genome. In that case, and especially when seed is the desired product to be harvested from the hybrid plants, it is typically useful to ensure that male fertility in the hybrid plants, which contain the genetic determinants responsible for male sterility, is fully restored. This can be accomplished by ensuring that the male parents have appropriate fertility restorer genes which are capable of restoring the male fertility in hybrid plants that contain the genetic determinants responsible for male sterility. Genetic determinants for male sterility may be located in the cytoplasm. Examples of cytoplasmic male sterility (CMS) were for instance described in Brassica species. However, genetic determinants for male sterility can also be located in the nuclear genome. Male sterile plants can also be obtained by plant biotechnology methods such as genetic engineering. A particularly useful means of obtaining male sterile plants is described in WO 89/10396 in which, for example, a ribonuclease such as a barnase is selectively expressed in the tapetum cells in the stamens. Fertility can then be restored by expression in the tapetum cells of a ribonuclease inhibitor such as barstar.
  • Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may be treated according to the invention are herbicide-tolerant plants, i.e. plants made tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation, or by selection of plants containing a mutation imparting such herbicide tolerance.
  • Herbicide-tolerant plants are for example glyphosate-tolerant plants, i.e. plants made tolerant to the herbicide glyphosate or salts thereof. For example, glyphosate-tolerant plants can be obtained by transforming the plant with a gene encoding the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Examples of such EPSPS genes are the AroA gene (mutant CT7) of the bacterium Salmonella typhimurium, the CP4 gene of the bacterium Agrobacterium sp., the genes encoding a petunia EPSPS, a tomato EPSPS, or an Eleusine EPSPS. It can also be a mutated EPSPS. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate oxidoreductase enzyme. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate acetyl transferase enzyme. Glyphosate-tolerant plants can also be obtained by selecting plants containing naturally-occurring mutations of the above-mentioned genes.
  • Other herbicide-resistant plants are for example plants that are made tolerant to herbicides inhibiting the enzyme glutamine synthase, such as bialaphos, phosphinothricin or glufosinate. Such plants can be obtained by expressing an enzyme detoxifying the herbicide or a mutant glutamine synthase enzyme that is resistant to inhibition. One such efficient detoxifying enzyme is, for example, an enzyme encoding a phosphinothricin acetyltransferase (such as the bar or pat protein from Streptomyces species). Plants expressing an exogenous phosphinothricin acetyltransferase have been described.
  • Further herbicide-tolerant plants are also plants that are made tolerant to the herbicides inhibiting the enzyme hydroxyphenylpyruvatedioxygenase (HPPD). Hydroxyphenylpyruvatedioxygenases are enzymes that catalyse the reaction in which para-hydroxyphenylpyruvate (HPP) is transformed into homogentisate. Plants tolerant to HPPD-inhibitors can be transformed with a gene encoding a naturally-occurring resistant HPPD enzyme, or a gene encoding a mutated HPPD enzyme. Tolerance to HPPD-inhibitors can also be obtained by transforming plants with genes encoding certain enzymes enabling the formation of homogentisate despite the inhibition of the native HPPD enzyme by the HPPD-inhibitor. Tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding an enzyme prephenate dehydrogenase in addition to a gene encoding an HPPD-tolerant enzyme.
  • Still further herbicide-resistant plants are plants that are made tolerant to acetolactate synthase (ALS) inhibitors. Known ALS-inhibitors include, for example, sulphonylurea, imidazolinone, triazolopyrimidines, pyrimidinyloxy(thio)benzoates, and/or sulphonylaminocarbonyltriazolinone herbicides. Different mutations in the ALS enzyme (also known as acetohydroxyacid synthase, AHAS) are known to confer tolerance to different herbicides and groups of herbicides. The production of sulphonylurea-tolerant plants and imidazolinone-tolerant plants has been described in the international publication WO 96/033270. Further sulphonylurea- and imidazolinone-tolerant plants have also been described, for example in WO 07/024,782.
  • Other plants tolerant to imidazolinone and/or sulphonylurea can be obtained by induced mutagenesis, by selection in cell cultures in the presence of the herbicide or by mutation breeding. Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are insect-resistant transgenic plants, i.e. plants made resistant to attack by certain target insects. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such insect resistance.
  • In the present context, the term “insect-resistant transgenic plant” includes any plant containing at least one transgene comprising a coding sequence encoding:
    • 1) an insecticidal crystal protein from Bacillus thuringiensis or an insecticidal portion thereof, such as the insecticidal crystal proteins listed online at: http://www.lifesci.sussex.ac,uk/Home/Neil Crickmore/Bl, or insecticidal portions thereof, for example proteins of the Cry protein classes Cry1Ab, Cry1Ac, Cry1F, Cry2Ab, Cry3Ae or Cry3Bb or insecticidal portions thereof; or
    • 2) a crystal protein from Bacillus thuringiensis or a portion thereof which is insecticidal in the presence of a second other crystal protein from Bacillus thuringiensis or a portion thereof, such as the binary toxin made up of the Cy34 and Cy35 crystal proteins; or
    • 3) a hybrid insecticidal protein comprising parts of two different insecticidal crystal proteins from Bacillus thuringiensis, such as a hybrid of the proteins of 1) above or a hybrid of the proteins of 2) above, for example the Cry1A.105 protein produced by maize event MON98034 (WO 07/027,777); or
    • 4) a protein of any one of 1) to 3) above wherein some, particularly 1 to 10, amino acids have been replaced by another amino acid to obtain a higher insecticidal activity to a target insect species, and/or to expand the range of target insect species affected, and/or because of changes induced in the encoding DNA during cloning or transformation, such as the Cry3Bb1 protein in maize events MON863 or MON88017, or the Cry3A protein in maize event MIR604;
    • 5) an insecticidal secreted protein from Bacillus thuringiensis or Bacillus cereus, or an insecticidal portion thereof, such as the vegetative insecticidal proteins (VIP) listed at: http://www.lifesci.sussex.ac.uk/home/Neil_Crickmore/Bt/vip.html, for example proteins from the VIP3Aa protein class; or
    • 6) a secreted protein from Bacillus thuringiensis or Bacillus cereus which is insecticidal in the presence of a second secreted protein from Bacillus thuringiensis or B. cereus, such as the binary toxin made up of the VIP1A and VIP2A proteins;
    • 7) a hybrid insecticidal protein comprising parts from different secreted proteins from Bacillus thuringiensis or Bacillus cereus, such as a hybrid of the proteins in 1) above or a hybrid of the proteins in 2) above; or
    • 8) a protein of any one of 1) to 3) above wherein some, particularly 1 to 10, amino acids have been replaced by another amino acid to obtain a higher insecticidal activity to a target insect species, and/or to expand the range of target insect species affected, and/or because of changes induced in the encoding DNA during cloning or transformation (while still encoding an insecticidal protein), such as the VIP3Aa protein in cotton event COT102.
  • Of course, insect-resistant transgenic plants, as used herein, also include any plant comprising a combination of genes encoding the proteins of any one of the above classes 1 to 8. In one embodiment, an insect-resistant plant contains more than one transgene encoding a protein of any one of the above classes 1 to 8, to expand the range of target insect species affected or to delay insect resistance development to the plants, by using different proteins insecticidal to the same target insect species but having a different mode of action, such as binding to different receptor binding sites in the insect.
  • Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are tolerant to abiotic stress factors. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such stress resistance. Particularly useful stress tolerance plants include:
    • a. plants which contain a transgene capable of reducing the expression and/or the activity of the poly(ADP-ribose)polymerase (PARP) gene in the plant cells or plants.
    • b. plants which contain a stress tolerance-enhancing transgene capable of reducing the expression and/or the activity of the PARG encoding genes of the plants or plants cells;
    • c. plants which contain a stress tolerance-enhancing transgene coding for a plant-functional enzyme of the nicotinamide adenine dinucleotide salvage biosynthesis pathway, including nicotinamidase, nicotinate phosphoribosyltransferase, nicotinic acid mononucleotide adenyl transferase, nicotinamide adenine dinucleotide synthetase or nicotinamide phosphoribosyltransferase.
  • Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention show altered quantity, quality and/or storage-stability of the harvested product and/or altered properties of specific ingredients of the harvested product such as, for example:
    • 1) transgenic plants which synthesize a modified starch, which in its physical-chemical characteristics, in particular the amylose content or the amylose/amylopectin ratio, the degree of branching, the average chain length, the side chain distribution, the viscosity behaviour, the gelling strength, the starch grain size and/or the starch grain morphology, is changed in comparison with the synthesized starch in wild type plant cells or plants, so that this modified starch is better suited for special applications.
    • 2) transgenic plants which synthesize non-starch carbohydrate polymers or which synthesize non-starch carbohydrate polymers with altered properties in comparison to wild type plants without genetic modification.

    The logP values were determined in accordance with EEC directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) on reversed-phase columns (C 18), using the methods below:
    [a]The determination was carried out in the acidic range at pH 2.3 using the mobile phases 0.1% aqueous phosphoric acid and acetonitrile, linear gradient from 10% acetonitrile to 95% acetonitrile.
    [b]The LC-MS determination in the acidic range was carried out at pH 2.7 using the mobile phases 0.1% aqueous formic acid and acetonitrile (contains 0.1% formic acid), linear gradient from 10% acetonitrile to 95% acetonitrile.
    [c]The LC-MS determination in the neutral range was carried out at pH 7.8 using the mobile phases 0.001 molar aqueous ammonium bicarbonate solution and acetonitrile, linear gradient from 10% acetonitrile to 95% acetonitrile.
    Calibration was carried out using unbranched alkan-2-ones (having 3 to 16 carbon atoms), with known logP values (determination of the logP values by the etention times using linear interpolation between two successive alkanones). The lambda-maX values were determined in the maxima of the chromatographic signals using the UV spectra from 200 nm to 400 nm.
    [d]The chemical NMR shifts in ppm were measured at 400 MHz, unless indicated otherwise in the solvent DMSO-d6 using tetramethylsilane as internal standard.
